Background@#In recent years, large amounts of data generated by patients have been accumulated on social media.We explored patients’ perspectives and experiences with vitiligo using web scraping data from the open internet community, NAVER Cafe. @*Objective@#To understand patients’ real concerns and thoughts about vitiligo. @*Methods@#Using vitiligo as a keyword, 1000 posts on NAVER Cafe were collected and categorized as follows: requests for recommendations for dermatology clinics; inquiries regarding vitiligo diagnosis, disease characteristics of vitiligo, and management of vitiligo; and advertisements. Essential contents were collected for each category to summarize patients’ perspectives and experiences. @*Results@#Of the 1000 posts, 284 were requests for clinical recommendations, 203 inquiries for diagnosis of their white spots, 132 inquiries regarding characteristics of vitiligo, 118 described experiences and emotions related to vitiligo, 105 inquiries regarding management of vitiligo, 103 advertisements, and 55 not related to vitiligo.Concerning the authors, 209 and 522 posts were written by patients and parents of children with vitiligo, respectively. @*Conclusion@#Patients with vitiligo have considerable concerns regarding their condition and actively communicate with each other through social media.

RESUMO
Background@#Micropigmentation is a medical tattooing procedure in which pigments are implanted into the superficial dermis using a manual or electrically driven needle. @*Objective@#We aimed to assess the benefit and risk of micropigmentation in the treatment of acral vitiligo refractory to the conventional treatment. @*Methods@#An open-label study was conducted from December 2018 to March 2019. A total of 12 patients with 20 acral vitiligo lesions were treated with micropigmentation using an electric tattooing machine. The micropigmentation treatment was repeated for a few sessions to achieve optimal pigmentation. Color matching between the lesion and peri-lesional skin was assessed using a 4-point grading scale (poor, fair, good, and excellent). @*Results@#Overall, 85% (17 of 20) showed excellent color matching after a median of 2 (range: 1∼5) treatment sessions. The post-treatment color was darker than the surrounding skin immediately after the procedure, but it gradually faded over time. Pain during the procedure was not mild, but local anesthetic injection was not required. Post-treatment erythema and swelling occurred, but they resolved within a few days. No allergic reaction to the pigment or koebnerization of the vitiligo was noted. @*Conclusion@#Micropigmentation could be a promising treatment option for refractory acral vitiligo. A few treatment sessions (i.e., retouch) may be required for desired outcomes. The crucial parts of micropigmentation are pigment selection and implantation depth. It does not require injection of local anesthetics and provides immediate treatment effects after the procedure.

RESUMO
BACKGROUND: As nonsurgical interventions for vitiligo are not always successful, various surgical modalities have been used in patients with refractory vitiligo. Of these, non-cultured epidermal suspension transplantation (NCES) was recently introduced to treat large recipient sites using cells from small donor tissue. OBJECTIVE: We assessed the effectiveness and safety of NCES as a surgical treatment for patients with refractory vitiligo. METHODS: We retrospectively reviewed 20 cases in 17 patients (11 females; median age 25 years) who underwent NCES from July 2015 through March 2018. Suction blisters (20 mm in diameter) were collected from the patient's inner thigh at a donor-to-recipient area ratio of 1:5. After the addition of 5 mL recombinant trypsin solution to the suction blisters, followed by incubation at 37℃ for 60 min, epidermal cells were manually scraped off the blister surface, and epidermal cell suspension was obtained by centrifugation at 1,500 RPM for 5 min. The suspension was applied to the vitiligo regions after epidermal ablation of those regions. Phototherapy resumed 1 month later. Treatment success was defined as ≥75% repigmentation of the surgical site, and all adverse events were noted. RESULTS: Overall, 85.0% of cases (17/20) exhibited treatment success. Adverse events included hyperpigmentation (20%) and surgical site infection (5%), but the treatment was tolerable in all cases. CONCLUSION: NCES is a reliable surgical option for patients with vitiligo refractory to nonsurgical treatment. Large areas of vitiligo can be treated by NCES, and use of this technique should be encouraged in Korea.
